Laws of Freach

The following is one possible solution to this challenge.

using System;

int[] array = new int[] { 4, 51, -7, 13, -99, 15, -8, 45, 90 };

int currentMinimum = int.MaxValue; // Start higher than anything in the array. 

foreach(int value in array)
{
    if (value < currentMinimum)
        currentMinimum = value;
}

Console.WriteLine(currentMinimum);


int total = 0;

foreach(int value in array)
    total += value;

float average = (float)total / array.Length;

Console.WriteLine(average);
